INTRODUCTION Concrete is a composite material composed of water, coarse granular material (the fine and coarse aggregate or filler) embedded in a hard matrix of material (the cement or binder) that fills the space among the aggregate particles and glues them together. Concrete is widely used for making architectural structures, foundations, brick or block walls, pavements, bridges or overpasses, highways, runways, parking structures, dams, pools/reservoirs, pipes, footings for gates, fences and poles and even boats. Concrete is used in large quantities almost everywhere mankind has a need for infrastructure Even if rubber tyre aggregate was used at relatively low percentages in concrete, the amount of waste tyre rubber could be greatly reduced due to the very large market for concrete products worldwide. Therefore the use of discarded tyre rubber aggregates in concrete shows promise for developing an additional route for used tyres. According to the reports, globally 15 million tonnes of waste tyres are generated annually, out of which India contributes one million tonnes. Main objective of this project is to determine “TO STUDY THE IMPACT OF CRUMB RUBBER ON YOUNG’S MODULUS OF CONCRETE”. In this study we will find the impact of crumb rubber on young’s modulus of concrete by replacing fine aggregates with 5%, 10%, 15% and 20% rubber. 2 – MATERIAL AND DESIGN METHODOLGY 2.1. Materials The properties of material used for making concrete mix are determined in laboratory as per relevant codes of practice. Different materials used in present study were cement, coarse aggregates, and fine aggregates, in addition to plastic bags and iron slag. Ordinary Portland cement - Ordinary Portland cement of grade 43 was used in concrete. OP cement does not contain any pozzolanic material. Consistency of Cement was found to be 29% and it was well sound with a tensile strength of 3.8 N/mm 2 after 7 days and compressive strength of 48 N/mm 2 after 28 days. Aggregates - Fine aggregate: fine aggregate was used locally available. It was sieved through 2.36mm IS sieve. Fineness modulus was 3.39, and of zone - II Abstract - Large quantities of scrap tires are generated each year globally. This is dangerous not only due to potential environmental threat, but also from fire hazards and provide breeding grounds for rats, mice, vermin’s and mosquitoes. Over the years, disposal of tires has become one of the serious problems in environments. Land filling is becoming unacceptable because of the rapid depletion of available sites for waste disposal. In order to prevent the environmental problem from growing, recycling tire is an innovative idea or way in this case. In this, we study the impact of crumb rubber on Young’s modulus of concrete. A modified concrete is prepared by replacing fine aggregates in concrete with rubber aggregates by varying the replacement proportion from 0% to 20% with increment of 5%.To manufacture a rubber concrete block by altering the percentage proportion of crumbled rubber aggregates in place of fine aggregates and study its properties and perform the tests. Concrete of grade M30 is prepared.
